TO ALL' WI-IOM IT MAY CONCERN:

Be it known that I,'NATHANIEL PULLMAN, of New Oregon, in the county of Howard, and State of Iowa, have invented a new and improved-Device for Replacing Cars upon the Track; and I do hereby declare that the following` is a full'and exact description of the same, reference being had to the accompanying drawings,

and to the letters of reference marked thereon.

This invention relates to a novel device for replacing cars upon the track, which consists, principally, in-a new form of step or shoe, and also in a new arrangement for attaching the supplemental rails to the main track, as will be fully described hereinafter.' I

In the drawings, A represents the track-proper, upon which it is desired to replace the cars.

n B represents the shoe, which is constructed in two parts, as shown, being connected by means ot' the bolt b, which latter may be in ade of any proper form, and be secured in any proper manner. In this case, h'owever, itis ma-'le round, and is secured in place by means of the key b1', which passes through a slot in its end,

as shown. Oneside of the shoe is provided with projections, b2, which lit into corresponding sockets in the other side, a perfectly ,secure connection being thus made. The lower part of the shoe is constructed with the l clamps b3 b3, of such forni as to accurately t the track-rail. The upper part is constructed with parallel sides upon the end which receives the short rail E, this arrangement being intended for the purpose of preventing the latter from moving to either side. Upon the other end, however, the sides diverge, as shown, to allow the v rail D to move freely in either direction to a certain extent.

It willvbe also observed that the inner side'ot` the shoe is made lower than the o uter, this construction being necessary to allow the' flange of the car-wheel to pass. It also' gives the greatest strength to the outside, it being t'he part liable to the greatest strain. A

The bottom of socket of shoe inclines in each direction at a proper angle to receive the supplemental rails D E in such manner that they restjirm-ly upon it. C represents a supplementalshoe or step, which is constructed with the base, c, the upper 'part being in all respects like the shoe B, excepting that `the bottom is inclined in an upward direction, andl toward the shoe B. It is essential that the shoeshould be properly secured in some manner, either to u. tie or'to other timber, suitably-placed. It may herprevidedvwith pointed pins, cast with it, or it may have pins driven in, and be fastened in that way. In this shoe the end ofthe rail D is firmly held by the parallel sides. D D"represent supplemental rails, t'he latter of which is taperedo-ii` to allow the car-wheel to mount upon it. These rails are provided with holes, (which are bevelled inA each direction,) and are fastened to the shoes B C by me'ans of the pins 0l d, by which construction a certain amount of play is 'allowed in either direction.v These pins are attached by means of chains and staples to the shoes, andthus are always retained in place, and cannot be lost. Both ends of the r-ail D and the upper end of the rails D are,

rounded oli` upon their upper corners, in order to prevent all possibility of the flange of the car-wheel catching upon them. The lower corners, however, are left nearly square, in order to secure as much bearing-surface as possible upon the shoe. E represents the short rail, by means of which the cars are easeddown on tothe track.

It will hte observed that the inside of the rail is chamt'ered oil'. This form is V intended to prevent all pos-l sibility ofthe wheels jumping the track, for if the rail were straight upon this edge, the Wheels would be extremely liable to strike upon it and mount over it, but by this construction the danger is avoided. This rail is held iirlnly in place, and prevented from moving laterally, by means of the sides of the shoe B, in which it snugly lits, it being also secured by a pin, d, in a similar manner to the other. It thus rendered unnecessary vto fasten this rail to the main track in any manner.

This device is made right and left, one' part being designed for use upon one side of the track, and the other upon the other side, by which means each side can be used independently of the other: It often happens that this is desirable, hence a great objection arises to devices for this purpose, in which both sides are joined together. i i

For ordinary purposes, ,the rail D and supplemental shoe C may be dispensed with, the rail D being attached directly to` the sh`oe B, but in cases where the cars are olf at some distance from the'track it will be necessary `to use both. V

From this description, the operation of 'my device will be easily understood. When it isd'csired to use it to replanc cars o thetraclt, the'shoeB, hating been sepnraterhis placed nponthe track and united by means of the key b, by which means it is firmly clamped to the ruil. The supplemental rails are then attached, as described.' The extension-rail D and shoe C may be used or not, as svnecessary. If desired, the fiei'ico upon one track `muy be plnced in advance of the other, as they cen be used independently of cnt-h other. An extremely simple'and efficient arrangement is thus provided. It may be placed insmull c ompuss, and easily carried, and it cannot get out of order. A i

v Having thus'fully d'escribedl my invention, what I claim ns newhand desire t'o secure by Letters Patent, in 1. The shoe B, constructed in two parte, with parallel-arid, diverging slideqnd having clamps b und bolt b, substantially as ilescribed. Y I

2. The shoe G, constructed with prallel and diverging sides,'the,outer of which is higher than the inner, as and for the purpose-described. i i

3.) The combination of 'shoes B C, rails D Dfi E., when constructed as described, adapted to the ra'rls A A, and operated substantially as set forth. l
